LEONARD LOGAN, OF PLYMOUTH, INDIANA.

WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 427,775, dated May 13,1890.

I Application filed September 2,1889. Serial No. 322,657. (No model.)

To aZZ whom it may concern:

Be it known that I, LEONARD LOGAN, a citizen of the United States,residing at Plymouth, in the county of Marshall and State of Indiana,have invented a new and useful Improvement in W aShing-Machines, ofwhich the following is a specification.

My invention relates to that class of washing-machines in which theclothing to be washed is placed in a perforated cylinder partlyin'nnersed and arranged to revolve in hot suds.

The object of my improvement is to provide a washing-macl'line of theclass mentioned arranged so as to set on an ordinary kitchen-stove, andcontaining in a compact form the washing-cylinder and its water-tank, asteanrmotor, and a steam-generator, all as hereinafter fully described.

The accompanying drawings illustrate my invention.

Figure 1. represents a central longitudinal section of the machine; Fig.2, a transverse section at a, Fig. 1; and Fig. 3 a similarsection at b,Fig. 1. Fig. 4 shows a View in perspective of the complete machine.

A is an oblong rectangular hollow vessel adapted to set on akitchen-stove and having double walls and a double bottom and atransverse partition a, thus forming the open intorior compartments 13and C and an annular steam-tight compartment D.

E is the washing-cylinder, which is constructed, in the usual manner,with perforated walls, and provided at each end with short shafts f andg, which rest in suitable bearings in the ends of vessel A, the cylindernearly filling compartment B.

II is a steam-motor mounted in compartment 0 and secured to or connectedwith shaft f, so as to rotate the washing-cylinder E. I have illustratedone of the simpler .forms of rotary engines as a motor; but I do notwish to be understood as confining myself to this particular form ofmotor.

I is a steam-pipe provided with a stop-cock J, and connecting theannular compartment D with the motor.

K is an opening for introducing water into compartment D.

L is a safety-valve.

III is a cover for in closing the working parts.

The operation of my device is as follows: Compartment I3 is nearlyfilled with water havin soa in solution and com )artment D is partlyfilled with clear water through openin g K,which is then tightly closed.The articles to be washed are placed in cylinder E, and heat is thenapplied to the bottom of vessel A. The water in compartment B heats moreslowly than in compartment D, so that by the time the water is hot incompartment B a steam-pressure sufficient to run the motor has beengenerated in compartment D. Steam is now admitted to the motor throughpipe I, and the motor being started the washing-cylinder is rotated, thesteam being exhausted into compartment G, and passing from thence overpartition a into compartment B.

I claim as my invention In a washing-machine, the following ele ments,namely: a vessel having double walls with an annulur closed spacebetween them, and two interior compartments, a perforated horizontalcylinder arranged to rotate in one of said interior compartments, and asteammotor arranged in the othercompartment and connected with saidannular closed space, all combined and arranged to co-operatesubstantially as and for the purpose specified.

LEONARD LOGAN.
